摘要
Isocarboxazid irreversibly inhibits monoamine oxidase, so serotonin is not broken down, and nortriptyline is a tricyclic antidepressant that blocks noradrenaline and serotonin reuptake. Together they can precipitate serotonin syndrome with hyperthermia, agitation, clonus and autonomic instability, which can be fatal.
用白話說明這項交互作用的意義
Isocarboxazid and Nortriptyline are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Isocarboxazid belongs to Central Nervous System; Nortriptyline belongs to Central Nervous System.
為什麼會發生
Excess serotonergic activity (MAO inhibition plus serotonin reuptake or receptor effects)
處置方式
Do not co-administer. Leave at least 14 days after stopping isocarboxazid before starting nortriptyline, and at least 14 days after stopping nortriptyline before starting isocarboxazid.
